+This parameter is available only in the cloud-based service.

 ### -JournalingReportNdrTo
-The JournalingReportNdrTo parameter specifies the email address to which journal reports are sent if the journaling mailbox is unavailable. By default, if this parameter is left empty, Exchange continues to try to deliver the journal report to the journaling mailbox. We recommended that you use a dedicated (non-user) mailbox as the argument to JournalingReportNdrTo.
